The successor to the famous Scubapro Gorilla fins of the 1980s, this new version of the award-winning Seawing Nova has been fine-tuned to provide a slight increase in stiffness and snap. They give you more power, more speed and even better frog-kick-ability while at the same time ensuring they still offer the legendary comfort and efficiency of Seawings! The Gorilla's are ideal for those diving in demanding conditions! The secret to the Gorilla Nova design is the articulated joint that allows the blade to pivot allowing the entire blade to generate thrust. Pivot control technology ensures the most efficient angle of attack is maintained no matter how hard or softly you kick, generating thrust without drag or wasted energy. Gorilla Nova incorporates clean water blade geometry for optimum propulsion. Water is free to flow onto the working section of the blade, resulting in drag reduction and a thrust increase. Variable pivot control ribs insure that the most efficient angle of attack is maintained across all strengths of kick.
